Dislocation-Mediated Melting in Superfluid Vortex Lattices (2008)
Gifford, S. Andrew, Baym, Gordon
We describe thermal melting of the two-dimensional vortex lattice in a rotating superfluid by generalizing the Halperin and Nelson theory of dislocation-mediated melting. and derive a melting...
Non-uniform vortex lattices in inhomogeneous rotating Bose-Einstein condensates (2006)
Baym, Gordon, Pethick, C. J., Gifford, S. Andrew, Watanabe, Gentaro
We derive a general framework, in terms of elastic theory, for describing the distortion of the vortex lattice in a rotating Bose-Einstein condensate at arbitrary rotation speed and determining the...
Structure of vortices in rotating Bose-Einstein condensates (2006)
Watanabe, Gentaro, Gifford, S. Andrew, Baym, Gordon, Pethick, C. J.
We calculate the structure of individual vortices in rotating Bose-Einstein condensates in a transverse harmonic trap. Making a Wigner-Seitz approximation for the unit cell of the vortex lattice, we...
Gifford, S. Andrew, Baym, Gordon
We establish the general equations of motion for the modes of a vortex lattice in a rapidly rotating Bose-Einstein condensate in three dimensions, taking into account the elastic energy of the...
